Halo 4 is set four years after the events of Halo 3, marking the return of iconic hero Master Chief and representing the beginning of a brand new saga.

In addition to the single-player campaign, Halo 4 will feature a robust multiplayer offering through War Games, which will take place on the Spartan training ship Infinity and will tie into the game's story.

343 Industries recently announced that there will be downloadable class specialisations available for multiplayer, as well as a War Games Map Pass providing access to future DLC maps.
